The Virginia Supreme Court declared the state's anti-spam law unconstitutional Friday and reversed the conviction of a man once considered one of the world's most prolific spammers.

The court unanimously agreed with Jeremy Jaynes' argument that the law violates the free-speech protections of the First Amendment because it does not just restrict commercial e-mails — it restricts other unsolicited messages as well. Most other states also have anti-spam laws, and there is a federal CAN-SPAM Act as well, but those laws apply only to commercial e-mail pitches.

The Virginia law "is unconstitutionally overbroad on its face because it prohibits the anonymous transmission of all unsolicited bulk e-mails, including those containing political, religious or other speech protected by the First Amendment to the U.S. Constitution," Justice G. Steven Agee wrote.

Agee wrote that "were the Federalist Papers just being published today via e-mail, that transmission by Publius would violate the statute." Publius was the pseudonym used by Alexander Hamilton, James Madison and John Jay in essays urging ratification of the Constitution.
